Struct scylla_cql::frame::protocol_features::ProtocolFeatures

#[non_exhaustive]
pub struct ProtocolFeatures {

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rate_limit_error: Option<i32>

lwt_optimization_meta_bit_mask: Option<u32>

tablets_v1_supported: bool

Implementations

impl ProtocolFeatures

pub fn parse_from_supported(supported: &HashMap<String, Vec<String>>) -> Self

pub fn add_startup_options( &self, options: &mut HashMap<Cow<'_, str>, Cow<'_, str>>, )

pub fn prepared_flags_contain_lwt_mark(&self, flags: u32) -> bool

Trait Implementations

impl Clone for ProtocolFeatures

fn clone(&self) -> ProtocolFeatures

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProtocolFeatures

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProtocolFeatures

fn default() -> ProtocolFeatures

Returns the “default value” for a type.

impl PartialEq for ProtocolFeatures

fn eq(&self, other: &ProtocolFeatures) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
